Subject: [Linux-cluster] Failover not happening when SAN connectivity failed
Hi All,
We have a cluster setup with Redhat Cluster Suite on RHEL5 OS.
SAN is one of the resource configured in the cluster.
We observed that if the SAN connectivity is lost on a given node then resources
are not getting failovered to second node. How to resolve this problem?
Regards,
Prasad.
